1 Adjusting the gain level

2 Additional Features

The AM6162L has an adjustable gain

control. You can adjust the gain level

depending on your signal strength. Use a

at-headed screwdriver to adjust the gain.

1. Turn clockwise to increase the gain level

(max 16dB)

2. Turn anticlockwise to decrease the gain

level (min 0dB (no signal amplication))

Short circuit protection

For added safety the AM6162L has built-

in short circuit protection. Should a short

circuit be detected, the amplier will shut

downin order to prevent any possible

damage. Should this occur, all outputs will

be switched off but the power LED will

remain lit.

To reset the system following a short

circuit, simply remove all outputs and

inputs, switch off the amplier and remove

the power cable from its socket for approx

30 seconds.

You should then reconnect the amplier

outputs one by one until you can  nd

which output is causing the short circuit.

3 Installing the AM6162L Indoor amplifier

Method 1

TV SIGNAL DISTRIBUTION

1 Connect your UHF/VHF aerial downlead

(tipically via an aerial wall socket) to the ANT

socket on the amplier.

2 Connect up the four TVs to the TV socket

on the AM6162L

Method 2

TV/VCR/DTT

1 Connect your UHF aerial downlead to the

aerial input VCR & DTT receiver.

2 Connect an aerial y-lead from the aerial

output on the DTT receiver to the aerial UHF

input of the AM6162L.

3 Connect up two TVs to the TV socket on

the AM6162L

Method 3

TV/VCR/DTT (digital Terrestrial

Television) DISTRIBUTION

1 Connect your UHF aerial downlead to the

aerial input on the DTT receiver

2 Connect an aerial y-lead from the aerial

output on your DTT receiver to the aerial

input on your VCR recorder and its output

connect to the AM6162L UHF input

3 Connect an aerial y-lead from the aerial

output of VHF Modulator to the antenna

input of AM6162L

4 Connect up four TVs to the TV socket on

the AM6162L.

Once connected you can tune each

television to traditional terrestrial channels,

a channel VCR viewing and a channel for

DTT viewing

Some DTT/SAT receivers do not have a RF

output channel. Then use the external

modulator (MV7125, see g 3)

If you are receiving poor DTT reception then

connect the AM6162L before your DTT

receiver to help boost the signal strenght.

In most cases, poor DTT reception can

only be cured by acquiring a suitable aerial

(see troubleshooting) or waiting until DTT

coverage improves in your area.

4 Adjusting the gain level

If you are still experiencing reception

problems after installing the AM6162L,

please refer to the troubleshooting guide

below:

No picture or sound

No signal is reaching your television due

to a possible break in the aerial signal

path. Ensure that all equipment has been

switched on (including the AM6162L

amplier) and that all coaxial connectors

have been  tted correctly.

Snowy picture

Your signal strength is still too weak. Ensure

that your aerial is positioned correctly

(pointing at your local TV transmitter).

Ageing aerials become corroded by the

weather, which may need to be replaced.

Also check that the position of the aerial

has not been mis-aligned by weather,

birds, or loft activity.

‘Herringbone’ pattern

‘Herringboning’ is generally caused by

too strong signal or possibly by local high

power transmitters such as CB, amateur

or taxi radios. Your TV sound may be

affected as well as the picture. Use a

signal attenuator (available from your local

electrical retailer) to reduce the gain of

your aerial signal and improve your picture.

If you are located very close to your local

television transmitter, point your aerial

at an alternative transmitter in order to

receive a more suitable level signal.

Problems with DTT

Unlike analogue terrestrial television, it is

not possible to view DTT channel under

weak signal strength conditions.

Therefore, typically you will either receive

DTT channels with a clear picture and

sound or you will not receive any channels

at all.

Sometimes, an insufcient digital signal

can cause occasional blocking, freezing or

complete loss of picture. Some roof aerials

may not be suitable for digital terrestrial

television.

Ensure that you have tted a suitable

wideband, high gain aerial to help improve

signal quality to a suitable level for clear

DTT reception.

Blocking, freezing or complete loss of

picture can also occur when a digital signal

is too strong.

If your signal is too strong then connect

your DTT receiver directly to the UHF aerial

downlead, then connect the AM6162L

amplier to your DTT receiver output

followed by your remaining equipment.

Problems with satellite television

If you are experiencing any problems with

your satellite television picture, check

that all cables and connectors have been

 tted correctly. If the problem persists it

is probably due to the dish alignment or

a temporary problem with the channel

transmissions. Please contact your local

satellite dealer if the problem persists.
